TOY WHEEL Filed July 26, 1930 INVENTOR fl Z 65-; ATTORNEY Patented Feb. 13, 1934 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to new and useful improvements in toy wheels.

It is one of the principal objects of my invention to provide for a toy wheel an axial bushing 5 which is adapted to receive, without change,

either a loose or a driving spindle.

Another object of my invention is to provide a dual disc toy wheel in which the discs are locked together by indentations produced in them by the 1 forming tool of a punch press. This is a cheaper and more satisfactory method of securing them together than by welding or riveting operations.

Other important and incidental objects will be brought out in the following specification and particularly set forth in the subjoined claim.

In the accompanying drawing illustrating my invention, Figure l is a side elevational view of a toy Wheel of the disc type, showing the separate indentations for locking the discs together. 20 Figure 2 is a sectional View taken through said Wheel on the line 22 of Figure 1. Figure 3 is a diametric sectional view taken through one of the wheel discs. Figure 4 is a side view of the split bushing before it is punch pressed in place within the discs. Figure 5 shows a side and an end View of a spindle upon which a locking ear has been formed. And Figure 6 is a side view of a toy disc wheel in which each disc is formed with a single annular indentation for locking purposes.

Referring to the accompanying drawing for a detailed description of my invention, the numerals 1 and 2 designate the two opposed discs of a toy Wheel, which may also be of a spoke or other type. Each disc is dished, as shown in Figures 2 and 3, to form a central conical portion that contains an axial bushing receiving hole 3.

These discs 1 and 2 terminate at their outer edge portions in tapered rim parts 4 to receive a rubber tire 5.

For the purpose of locking the discs 1 and 2 together, there is formed in the first, by a punch press operation, indentations 6 that enter depressions 7 formed by the same operation in the disc 2. Or there may be formed in the disc 1 a single annular indentation 8 that is pressed into an annular depression formed in the disc 2 to receive it as shown in Figure 6. Whether the indenta- 50 tions are plural, as shown in Figure 1, or annular as disclosed in Figure 6, they provide a cheaper and more satisfactory means for locking the discs together than rivets or welds.

In the same punch press operation that unites the discs 1 and 2, a bushing 9 is secured within their central holes 3. As shown in Figures 2 and 4, thus bushing comprises a split metal sleeve whose free axial edges are formed at the middle portions to provide a rectangular slot 10. The punch press operation which forms the indentations in the discs 1 and 2, turns the end edges of the split sleeve 9 against the middle portions of the discs, as shown in Figures 1 and 2, to firmly secure the sleeve between them. 7

Being positioned within the hollow central part of the wheel, the slotted portion 10 of the sleeve is free to open sufliciently to receive the locking ear 11 on a spindle 12 when the latter is inserted in the sleeve. After the ear 11 on the spindle enters that slot, it will be held tightly therein to provide a means of driving the wheel from the spindle. A spindle from which the car 11 has been omitted to make it a non-driving one, may also be inserted in the sleeve 9 to permit the wheel to turn freely upon it. Thus, it is seen that by the provision of my slotted split metal sleeve 9, a driving or a non-driving spindle may be inserted in it without any change being made in the sleeve or wheel.

Having described my invention, I claim:

In a toy wheel, the combination with a split axial bushing with its free axial edges punched to provide a pair of oppositely disposed U-shaped notches, a spindle insertible in said bushing, and an ear on said spindle, the notches in the bushing adapted to close around said ear to form a rectangular slot to tightly receive it.
